Ultraedit uses regular expressions (wildcards) for search and replacement.

Ultraedit is an alternative to notepad. Its advantage for notepad is self-evident. The following shows how to use a regular expression (wildcard) in ultraedit to find and replace common expressions.

Preparation: Before using a regular expression, you must set the regular expression.

1. Advanced-> Configuration-> Search-> Regular Expression Engine, select the ultraeidt-style Regular Expression

2. In the search and replace box, you must check the regular expression ".

A text file contains the following content:
